Hi all, I have one that might not be possible... What I'm doing is running a program with Open2, but need to send instructions to it when there is a single key-press. For that I'm using HotKey.pm from the Perl Cookbook. The problem I run into is I need to wait on While which causes my other process to hang untill it gets that key. I want it to just run it and take the key-presses as they come so to speak. Here's a simplified version of what I mean: 
Use HotKey.pm;
foreach $i (@things) {
 &program_running($i);
  while ($keyboard = readkey) { # This is the gotcha
   if ($keyboard =~ /b/) {
    print "you pressed b \n";
    }
  }
}

Is there any way to check for a key-press that does not wait? Sort of check it on the fly, or periodicly? TIA, Miker
